Dual Operator Dual-Wire Wrist Strap Monitor

       * Model for Options

* Safety Information

ESDMAN 001-8103 Work station monitor is designed to monitor the operation of two Wrist strap grounding systems and two work surfaces. This product has been designed and tested for use with dual conductor wrist straps and work surfaces grounding systems.

* Theory of Operation

The ESDMAN 001-8103 work station monitor is designed to monitor the operation of the wrist strap grounding systems of two operators. To accomplish this, it uses a DC current source to measure a loop electrical resistance. The system uses a special wrist band and ground cord that contain two independent elements. The 8103 monitor employs two selectable test voltages (9 and 16 volts) and resistance limits (10 Megohms and 35 Megohms) It also monitors the grounding of up to two work surfaces.

The model 001-8103 monitor performs a resistance measurement by applying an electrical current of less than 3 MA approximately every 2.0 seconds for 0.2 of a second in duration. The path for the current is through one conductor of the ground cord that contains a current-limiting resistor, through one side of the wrist band,through the skin of the wearer under the band, through the second side of the wrist band, through the second conductor of the ground cord that contains a current-limiting resistor, and finally back to the monitor.

* Selection of Test Voltage and Resistance limit & Resistance/Voltage switch selection

The model 001-8103 monitor allows for the selection of test voltages (9v or 16v) and resistance limits (10 Megohms or 35 Megohms). The additional ranges have been added to accommodate global Electrical Static Discharge requirements.
